vodka [1.7K]

well, in order to solve this we can put each marble into a fraction.

so for blue it would be 5 over 15 (5/15)

because there are 15 marbles in the bag but only 5 of them are blue!

but if you need a % then just divide the top by bottom

then you get a 33% chance of picking blue! hope this helps!

Lemur [1.5K]

Answer:

7/12

Step-by-step explanation:

12 sided die has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 as the sides.

Two digits are 10, 11, and 12.

Even numbers are 2, 4, 6, 8, 10, and 12.

So two digits or even numbers are 2, 4, 6, 8, 10, 11, and 12. (7 total numbers)

P(Two digits or even) = 7/12

Urgent please help..

The answer is 51.3

Explanation:
You’re finding angle Y, so write the SOH CAH TOA. the two sides your are given are the adjacent side to Y and the opposite side so you use tangent. You then get the equation tanY=10/8 Since you’re finding an angle you use inverse tangent so you get y=tan^-1(10/8) and then put that into the calculator!

Answer:

y=3x-7

Step-by-step explanation:

Two points on the line are (3,2) and (4,5) using the slope equation, 5-2/4-3=3/1

y-2=3(x-3)

(2+) y-2=3x-9(+2)

y=3x-7

a bird of species a when diving can travel four times as fast as a bird of species b top speed if the total speeds of these two

weeeeeb [17]

X will be the speed of species b and 4x will be the speed of species a:

x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h

If species b has a speed of 36 m/h, the speed of species a is 4 times that:

4 x 36 = 144 m/h.

Answer:

$\boxed {\bf A~=~36~m/h~and~B~=~144~m/h}$

Hope it helped,

Happy homework/ study/ exam!
